Murphy: The probability of “X” fluctuates in inverse proportion to our preparedness for “X.”

Goofy: Huh?

Murphy: If you don’t want it to rain, bring an umbrella. If you do, don’t.

Goofy: Gotcha!

Trifextra Weekend Challenge: Andy Rooney created something called “The 50-50-90 rule: anytime you have a 50-50 chance of getting something right, there’s a 90% probability you’ll get it wrong.” We want you to give us your own probability equation. Use whichever numbers suit you, and make it about whatever you like, but give us something to think about. In 33 words, of course.

BTW: I realize there are no numbers in my “probability equation.” Blame it on Murphy . . . “Anything that can go wrong will go wrong.” ;)
